"... one of our more obscure choices, the Cyzicus Room." Drok smiled and hooted his acceptance.
Just then, Grok came running from the elevator, but the lady at the counter held up her finger, and Grok immediately came to a halt.
"Now, now, Grok, you know that we don't force our patrons down paths they don't want to go down. The fates have decided that the young man is to follow a different path. I'm sure another patron will choose to join you in the Cave Room soon enough. Why, I think I might see one coming in the front door now. Back to your room, now, Grok."
Grok nodded and said "Me get it", his face showing his disappointment. Derrick realised that he must have been a good candidate for the room... but he just couldn't go through with it.
"Now, hurry to the Cyzicus Room. It's down the corridor to your right, all the way to the end. Got it?" Drok nodded, then turned left. "No, no. Over that way." The lady gestured, and Derrick, barely clinging onto his identity as his cock continued to taunt him, dashed down the corridor.
It was a surprisingly long, straight corridor. After a good few minutes of running, Derrick came to a large door, which looked far too big for the space it seemed to occupy. He pushed, but the door wouldn't budge - he found himself wishing he had the muscles he would have gotten from the steak.
In frustration, he banged his hands on the door, creating a loud, reverberating thud. A few moments later, the door opened, and Drok looked up... and up... and up at the giant that opened the door.
"Me get new room" Drok... Derrick said, and hoped it would be enough to explain.
It took a few more moments before Derrick realised that not only was this a true giant, but he had six arms! And boy, was he built. He had no idea what kind of being this was - he'd never heard of anything like this before - but it had to be better than being a caveman or a servant minotaur.
"Very well. Enter," the giant boomed, and Drok slipped through the door and into... a large clearing? He looked up, and saw what seemed to be the sky. He looked back at the door, and it seemed to stand in the middle of the clearing, with nothing supporting it. Things just seemed to be getting more strange with each new room...
Derrick knew he had to find something to trigger a new transformation, and soon - if he didn't, he'd become Drok completely.
The six-armed giant spoke again, "Go to grove, and eat the fruit of the Great Tree." He gestured off towards a particularly large tree with his second left arm.
Drok nodded, and began to run, Derrick's identity slipping a little further. A glance down confirmed his suspicions - his chest was now quite hairy, and his arms were starting to get longer. The temptation to stop, masturbate to orgasm, and then return to the Cave Room, was growing ever stronger, and he wasn't sure that he could run fast enough to reach the tree before the urges overwhelmed him completely.
